Answer :

We start with the equation

[tex]$$151 = (18 \times 8) + \text{unknown}.$$[/tex]

Step 1: Calculate the product.

Multiply [tex]$18$[/tex] by [tex]$8$[/tex]:

[tex]$$18 \times 8 = 144.$$[/tex]

Step 2: Substitute the product into the equation.

Replace [tex]$(18 \times 8)$[/tex] with [tex]$144$[/tex]:

[tex]$$151 = 144 + \text{unknown}.$$[/tex]

Step 3: Solve for the unknown.

To isolate the unknown, subtract [tex]$144$[/tex] from both sides:

[tex]$$\text{unknown} = 151 - 144.$$[/tex]

Step 4: Compute the subtraction.

Subtracting gives:

[tex]$$\text{unknown} = 7.$$[/tex]

Thus, the unknown in the equation is [tex]$7$[/tex].
